What happened to prices between 1971 and 1974
Between 1971 and 1974, the Consumer Price Index went from 40.5 to 49.3.
Cumulatively, prices increased 21.7%, which works out to an average of
6.77% per year. Put differently, a dollar in 1971 bought what
$0.82 buys in 1974: the 1971 dollar
lost 17.8% of its purchasing power over
these 3 years.
Consumer prices rose 4.4% in 1971, down from 1970’s 5.7% as
the recession that started in December 1969 finally cooled demand. The bigger
economic story came that August 15, when President Nixon closed the “gold
window” that let foreign governments exchange dollars for gold, ending the
Bretton Woods system that had anchored the dollar since World War II. The
same address announced a 90-day freeze on wages and prices, the first
peacetime controls the country had seen, an attempt to break inflationary
expectations without the slower grind of tighter money. The “Nixon Shock,” as
it came to be known, let the dollar float against other currencies for the
first time and set the stage for a wage-and-price-control regime that would
run in various forms into 1973. Politically, the country lowered its voting
age that year: the 26th Amendment, ratified July 1, extended the vote to
18-year-olds, capping a campaign built on the argument that men old enough to
be drafted to Vietnam were old enough to vote for the people who sent them.
The Postal Service, independent since 1970’s reorganization, raised
first-class postage from 6 to 8 cents that May. A median household earned
$9,028 in 1971, up from $8,734 the year before, while gas held near 36 cents
a gallon and a new home sold for a median $25,200. Consumer prices stood
309.1% above their 1913 level by year’s end, still years away
from the double-digit inflation the controls were meant to prevent.
Every 1971 amount converts to 1974 at the same ratio, 1.22: $1,000 becomes
$1,217, and $10,000 becomes $12,173.

Year by year: CPI and the value of $100 from 1971
$100 from 1971 had already become $103 by
1972, on its way to $122 in 1974; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 11.0% in 1974, and the smallest rise was 3.2% in 1972.
In 1974, prices rose 11.0% and $100 from 1971 had the buying
power of $122; the year's average CPI of 49.3 is the level
behind every 1974 figure on this page.
1974 was the year the postwar economy broke its old rules. Consumer prices
rose 11.0%, the fastest annual increase since 1947, as the Arab oil embargo
that ran from October 1973 to March 1974 roughly quadrupled the price of
crude oil worldwide. Gasoline, which had averaged 38.5 cents a gallon in
1973, jumped to 53.2 cents, and shortages forced many states into odd-even
rationing at the pump. Nixon’s wage and price controls, in place in some form
since 1971, expired at the end of April, removing the last brake on prices
just as the oil shock hit. Nixon himself resigned in August over Watergate,
and Gerald Ford’s response to inflation, a voluntary “Whip Inflation Now”
campaign built around lapel buttons, became a symbol of how little
conventional politics could do against the problem. Prices kept climbing even
as the economy weakened: a recession that started in November 1973 dragged
on, the Dow fell to a bear-market bottom of 577.60 in December, and
unemployment was already rising toward the 9% it would reach in 1975. The
combination of rising prices and a shrinking economy gave the decade its
name: stagflation.
